I am getting about 3 blocks rejected for everyone that I find on my 280x. Anyone else having this issue?
I also can only get my 280X to mine. My 270X will not mine just HW errors and my other pc with Nvidia cards also nothing but HW.
What settings you use for your 280x?
I have my shades set to 2048 and shader mul set to 8.
Right now I show 32 accepted and 96 rejected.
I believe that cgminer info is incorrect right now so it is actually 16 found and 48 rejected. If you notice that cgminer accepted /rejected is always an even number.
